Answer:
The local and global extrema are: (-3,0), (0,-1.62), and (3,0)
Step-by-step explanation:
To solve this, we can use a graphing calculator.
The graph of the function looks as it is shown on the image.
Local extrema is defined as the highest/lowest y-value in a general area, while global extrema are the highest/lowest defined y-value on the function.
This graph shows that the highest points (as it is tied at y=0) are (-3,0) and (3,0), so they would be both local and global maximum.
Additionally, the local min is seen to be at (0,-1.62). This is also a global minimum as this function is not given a defined domain, so it can be assumed that the domain of this function is (-∞,∞). Global extrema can only occur at defined values, so the end points of -∞ and ∞ can be ignored.
Answer:
$1
Step-by-step explanation:
because of the dollar it makes sense to be a dollar
Answer: 32 hours
Step-by-step explanation: 51/6 = 8.5
So, Erica makes 8.5 dollars per hour. 272/8.5 = 32. Thus, Erica will need 32 hours.
